APPARATUS rois'I RAISING warns.

Tov all 'whom it may concern.'

Be it known that I, WILLIAM T. CRosLEN, a citizen of th@J United States, residing at Oklahoma city, in the vzounty of Oklahoma vention will be set forth' in the ensuing description.

One embodiment of the invention in practical form is shown by the accompanying drawings, in .which- Figure 1 1s a sectional view of 'a well, showing the improved apparatus installed for use. Fig.A 2 is a sectional view of a cass ing and associated parts, which are submerged i-n the water supply. Fig. 3 is an enlarged elevation view in the saine direction as Fi l, showing improved mechanism for contro ling compressed air. Fig. 4 is an elevation view, on a little larger scale and in the direction of the ari'ow 4, of parts shown in Fig. 3. Fig..5 is a sectional view in the same direction as Fig. 4 and taken on the line 5- 5 of Fig. 3. 1

Referring to the several figures, in all of which like characters'of reference designate like parts, the improved apparatus includes al cas1ng6 which is submerged in the water supply and adaptedto withstand internal fluid pressure, the lower wall of this casing having one or more openings 7 provided with valves 8. In this instance, the casing 6 is supported by blocks 9 resting on the bottom 10 of the well 11, but it may be supported in any other suitable manner, such, for examp1e, ,as suspending it by certain pipes p which lead to and from it.

A pipe 12 leads from a tank 13 or other source of cgmpressed air )into the casing 6,

haust pipe 16 leads from the upper part of. the casing 6, and is provided at its outer end with a valve 17 whose opening may be adjusted .to causebaek pressure of air for purposes'later shown. i

t In operation, water first nforcesthe valves 8 open and the casing 6, the displaced vSpecification of Letters Patent.

- and displacing the air as before. In arranging means for automatically opening and closing the inlet pipe 12, the exhaust pipe 16 leads through and permanently communicates with a pressure chamber 18, one wall of which is a yieldable diaphragm 19. The cast-metal body 20 of the chamber 18 has a depending portion A21 comprising a front part 21b integral therewith and a rear part 21 which faces lsaid front portion on, a' plane parallel with the diaphragm 19, these parts 21b and v21c being interposed by a yieldable diaphragm 22 and clamped thereagainst by screw bolts 23. lThe rear part 21c v is provided with two ports 24`and 25 whose inner ends face the diaphragm 22, the upper portion of the inlet pipe. 12 leading into the upper port 24 while the lower 'portion of said pipe leads from the lower port 25 to the casing 6. A plunger 26 is tted slidably in the front part 21b and adapted to be forced rearward to seat the diaphragm 22 in closing contact with the port 24 to close the inlet pipe 1 2, this plunger beingheld normally' forward away from said diaphragm by an embracing` helical spring 27. A pressure- -9'0 receiving plate 28` is arranged to be acted upon by the diaphragm 19 and is pivoted to lugs 29 on the depending portion 21, the pivotal portion of this plate having a depending integral nger 30 to act on'thev plunger 26.

i In furtherarrangement, an arm 31 carrying a gasket, valve 32 is pivoted to a depending lug 33 on the top 34 of the casing 6 and arranged .to seat said valve in-closing contact with the inner end of the exhaust pipe 16 insaid casing, the free end of this .arm having pivoted to it a vertical rod 35 upon which a float 36 is arranged to slide.l 7

The lower end of the rod.,35 is kept in vertiv'cal line by an arm 37 which is pivoted to a lug 38 on the bottom of the casing 6, and the pivotal end of this armis provided with a -weighted arm 39 adapted to rest at full 4 throw on either side of a vertical neutral line A-A. shown in Fig. 2. When the casing 6 seat the small diaphragm 22 to close the inlet pipe 12.V As the casing 6 fills with water, the ioat 36 gradually rises until temporarily arrested by a stop 40 on the upper Tend of the rod 35, and when the further rise of water increases the buoyancy of the float enough to overcome the gravity of the weighted arm 39 the latter is swung to and past the neutral line A-A with decreasing resistance and increasing momentum,'bring ing all connected parts to the position shown by the dotted representations in Fig. 2 andclosing lthe valve 32 against exhaust of air. With the exhaust pipe 16 closed below the pressure chamber 18 and the diaphragm 19 thereby relieved from back pressure, the spring 2'( withdraws the plunger 26 from the small diaphragm 22 and allows air to again enter the casing 6 through the pipe 12 to force the water up the pipe 14.

By permanently closing the valve 15 of the delivery pipe 14, the action of all parts of -the apparatus isfpermanently stopped; but by repeatedly opening said valve or leaving it open the air pressure drives out the water and allows the float 36 to descend until temporarily arrested by a stop 41 on the lower end of the rod 35, and when the further and final lowering of the water allows the float to overcome the gravity of the weighted arm 39 the latter is swung back to and past the neutral line with decreasing resistance and increasing momentum and brings all connected sition shown bythe full lines in Fig. 2.'

In order to avoid excessive pressure in the casing 6, the pipe 12 may be provided with a regulating valve 42 adapted to limit said pressure to a predetermined amount.`

An air-compressor 43 may be provided to supply airto the tank 13.

Having thus described the invention, I claim t 1. In apparatus of the character described, a casing adapted .to be submerged yin the water supply and having a valved inlet for water, a source of compressed air, a pipe leading from said source to the casing, an exhaust pipe leading from the casing, means for causing back pressure of the exhausting parts to the initial po-n air in said exhaust pipe, and means whereby said back pressure stops the entrance ofair from the said source. l

2. In' apparatus of the character' described, a casing adapted to 'be submerged in the water supply and having an inlet opening provided with a valve, a source of compressed air, a pipe leading from said source to the casing, an exhaust pipe .leading from the casing, means whereby the lowering of the water to a predetermined point in the casing opensthe exhaust pipe, means for causing back pressure in the exhaust pipe, and means whereby said back pressure stops the entrance of air `from the air source to thecasing.

Witness my hand this 6 day of June, 1914.
